Generating human-like motion for robots

Michael J. Gielniak, C. Karen Liu, Andrea L. Thomaz
2013 The international journal of robotics research  
Next in the pipeline, we avoid repetitive motion by adding variance, through exploiting redundant and underutilized spaces of the input motion, which creates multiple motions from a single input.  ...  Our goal is to improve the clarity of robot motion by making it more humanlike. We present an algorithm that autonomously synthesizes human-like variants of an input motion.  ...  In Experiment 1, we tested retargeting human motion onto two different models: a human model and the Simon robot model.  ...
